The capacity of the fungus Trichoderma harzianum CECT 2413 to colonize roots and stimulate plant growth wasanalyzed. Tobacco seedlings (Nicotiana benthamiana) transferred to Petri dishes inoculated with T. harzianum conidia showedincreased plant fresh weight (140%) and foliar area (300%), as well as the proliferation of secondary roots (300%) and trueleaves (140%). The interaction between strain CECT 2413 and the tomato-root system was also studied during the early stagesof root colonization by the fungus. When T. harzianum conidia were inoculated into the liquid medium of hydroponicallygrown tomato plants (Lycopersicum esculentum), profuse adhesion of hyphae to the plant roots as well as colonization of theroot epidermis and cortex were observed. Confocal microscopy of a T. harzianum transformant that expressed the green fluorescentprotein (GFP) revealed intercellular hyphal growth and the formation of plant-induced papilla-like hyphal tips. Analysisof the T. harzianum-tomato interaction in soil indicated that the contact between T. harzianum and the roots persisted over along period of time. This interaction was characterized by the presence of yeast-like cells, a novel and previously undescribeddevelopmental change. To study the molecular mechanism underlying fungal ability to colonize the tomato-root system, the T.harzianum transcriptome was analyzed during the early stages of the plant-fungus interaction. The expression of fungal genesrelated to redox reactions, lipid metabolism, detoxification, and sugar or amino-acid transport increased when T. harzianum colonizedtomato roots. These observations are similar to those regarding the interactions of mycorrhiza and pathogenic fungi withplants.Comisión Europea QLK3-CT-2002-02032Ministerio de Ciencia y Tecnologia AGL2000-0524 and BIO2003-03679Junta de Andalucía PAI CVI-10
